(54) Active liquid applicator for forming active film


(57) An active liquid applicator is provided which is designed to coat a surface of an electronic parts such as an oxygen sensor with an active liquid for forming an electrode. The liquid applicator (2) includes a nozzle head (21) and a nozzle tube (16). The nozzle tube (16) has disposed therein a pearmable member (18) which produces capillary attraction of an active liquid thereinto and feed it to the nozzle head (21) thereby enabling formation of a thin active film on the electronic part which has the thickness controllable with high accuracy.
